TO ALL WHOM IT MAY CONCERN:

Be it known that I, J. L. SMITH, of Tuscola, in the county of Douglas, and in the State of Illinois, have invented certain newand useful improvements in Car-Brakes; and do hereby declare that the following is a full, clear, and exact description-thereof, reference being hn-d to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification. I I

My invention consists in the construction of certain devices for operating the ordinary car-brakes.

In the annexed drawings, B represents the platform of the car, with the shaft F extending up above it at suitable distance to be operated by the brakesmam. Upon the upper end of this shaft is secured a metallic wheel, C, which lies horizontally, and has a series of shoulders, :22 x :11, formed upon its face, near the outer edge, and which extend around the entire wheel. Secured above the wheel, over the shaft, is a metal bar, E, which has two jaws, and which readily turns upon its shaft. Between these jaws is hinged the lever D, which has a shoulder, 2, formed upon its under side, so that it may catch behind the shoulders a: x on the face of the wheel 0. Lying upon the platform or car floor is a ratchet-wheel, G, stationar'ily connected to the shaft F, and which is secured in the desired position by a dog, H. I represents the chain or other device which connects the shaft to car-brake proper. I

In using this invention it is only necessary for the brakesman to allow the shoulder on the lever D to lie against one of the shoulders :1: upon the wheel 0, and turn his leveraround, which Winds the chain upon the shaft and forces the brakes against the wheels. When the brake is not reqnired,'the lever, by means o'fits hinge, is thrown upwards, the dog is released from its ratchet, and the shaft unwindsitself. I I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The arrangement of the wheel O, with its shoulders'a: x, lever D, hinged as shown, and with its shoulder z, in combination with the brake-shaft F, dog H, and ratchet G, in the manner and for the purposes specified.-

In testimony that I claim the foregoing I have hereunto set my hand this 7th day of February, 1867.

JAMES L. SMITH.
